" My invention relates'tocar truck's, the invention having foritsfobjectsthe provision of improved means for: assembling the. centergbearing' carrying members of) truck bol- 5 sters with the'underlying straps and a. construction I whereby the side frames take part have interengaging'holding formations. The key engages the strap and sleeve to maintain these holdlng formations 1n locking rela the side frame thus takingpart in maintaining the assembly of these two truckbolster members; though the invention isnotftjo be thus limited. VI also;provide limproved means for connecting the 'frame'sf],

The invention will be more fully en plaine'd in' connection with the accompanyw ing drawing in which Fig. 1 is a'view in elevation, partially in section on line 1- 1 of Fig. 2, illustrating the preferred {embodiment of the invention, a portion of the centerbearing beingalso illustrated; and'Fig.

cast in one integral 'structure'with its center bearing socket 2,-the side bearing elements 3, and the strut member 4 underlying the- ;member 1 and the socket thereof. Astra'p 5 underlies'the strut member and passes at its ends into the bores of, sleeves'6 formed at theends of the center bearing carrying member'L' Lugs-7 depend from the bolster member 1, theselugs being between and adjafoent the sleeves and engaging the top side of the strap to holdf'it down.

Keys S'are passed laterally through 'open- I ings that are formedin the sides of the sleeves, these keys desirably engaging the V The strap is. formed With-downwardly extendingtransverse horizontal ridges;9 at its ends; Thejsleeves are formed, with upwardly extending transverse horizontal ridgeslO in the bores thereof. These ridges form books, the hooks upon the strap en'- the sleeveand the adjacent end of the strap;

gaging the hooks that; are provided the sleeves "The keys being interposed' beltween the topside of'the strap :11 formed upon andwithin the upper portions'ofj the sleeves hold thestrapand the bolster mem ber ltin firm assembly; The keysr 'are desir 1 ably inthe forni' of flat bars arrangedparallel with the-ends of the s'trap," lwhereby,any",, tendency to shearing strains between the keys and strap is resisted.

The center bearing. carrying member 1 the truck. bolster .is 1 formed with upr ght grooves 12at the'sides ofeach gleaming ceive the keys '8 establishing. communication between" the bores of the sleeves and said;

openings'in the sides-of the sleeves that regreoves whereby "the keys may? be passed transversely through the sleeves. Side frames 13j'are provided, these "side frames having upright portions 14C that are. received in the grooves 12"whereby the center bear ing 'carrying member 1 serves; to assemble the u per port onsof thejs1de frames and" where y, withdrawal, of the keys is pre vented after the truck frames are assembled.

The lower portions of] 'sidelframes carry truck bolster supporting springs {15. These springs overlie -upwardly' facing frames are assembled. 1 These hooks closely underhethe springs to enable the springs tohold the link ends in said hooks.

Changes may bemade without from the invention. 7 Having thus describedmy invention, 1 claim:" '1 .f 1 A truck, bolster including the center departing bolster, and side p hooks16. which receive the ends ofla-lin k 17 whereby the lower portions of the side.
